I wanted to make this separate from the Vit D discussion. What do you mean by OTC meds (fever reducer, cough suppressant...)? Based on reading your posts over the years I know that you know this, but I'll type it anyway: OTC meds treat the symptoms not the virus/bacteria. They make you feel slightly better while your immune system battles the pathogen.
I'm not a medical doc, but based on your description, I would suggest that the several days of OTCs plus few days of D3 (about a week?) gave your immune system time to get the upper hand. The D3 probably didn't hurt, but I'd say it was the time that made the difference. One BUT here is that when we are sick we tend not to eat as well/much so supplementation can help our immune system as the days in bed stretch on.
EDIT: Older populations in care facilities might be nutrient deficient so that might bend the numbers. It seems like a good facility would perform regular blood work and adjust diet (including supplementation) as needed, but I'm not sure if that is a 'standard'.
Yes...the OTC meds were basically Nyquil & Tylenol for symptom control - and neither was was really doing much for symptom control anyway. My son & I were actually getting worse by the day and were contemplating a trip to urgent care (especially for the
respiratory problems). That's where we both did a modified "vitamin D3 hammer" (you can Google "vitamin D3 hammer" for further if you're interested). Within 24 hrs we
both felt much better with improvement on the respiratory issues and getting our appetites back - we could actually taste food again! So it was about 10 days for the both of us before we got back into the weight room/track and resumed training. As I mentioned, I lost ~12 lbs of muscle mass and virtually all CV fitness. My son lost some weight and quite a bit of fitness as well. But it was a welcomed challenge to get back into training after being so ill. About 3 weeks for me to get back to pre-illness level (my doc said expect 5-6 weeks for a
severe case of the flu at my age ), and my son, who runs sprints on the college track team, took about half that time.
Like I mentioned, I've never been this sick for 15+ years that I could remember. Back in 2017/18 during one of the worst flu seasons in decades (according to the CDC), I never got the flu nor did my son. And I was co-coaching my son during his senior year of HS and just about every other athlete & coaches that I was around was sick at one time or another. But this year we both come down with severe cases of the flu at almost the exact same time - strange.
Maybe it was placebo...maybe it was wasn't (I don't think it was). But that's why I made sure to introduce this as an
anecdotal and nothing more.
My daily dose before the flu was 1000 IU daily and then after the hammer, I'm now taking the tolerable upper intake level (ULs) for D3, which is 4000 IU daily. I plan on getting my levels checked next month (as should everyone) and I'll scale down during the summer as I usually can get adequate sun exposure.

The former CDC director recommends vitamin D for reducing infection risk from the
coronavirus:
Vitamin D supplementation reduces the risk of respiratory infection, regulates cytokine production and can limit the risk of other viruses such as influenza.
